Santiago Calatrava Valls

Among his latest projects we could mention 80 South Street, which is a residential skyscraper which has its name after its own address, and which is made of 10 city houses shaped as cubes placed one on top of the other. These houses have a pattern resembling a ladder and so each house has a roof of its own. This so-called ‘townhouse in the sky” type of design has brought Mr. Calatrava a lot of clients, despite the enormous price of $30.000.000 for each cube in particular.

Calatrava is also the author of what was once an approved project, but it is currently canceled: that of the Chicago Spire skyscraper in the city of Chicago. It was abandoned out of financial reasons. The building was intended to be constructed starting in 2007, in August, and to be finished in the year of 2011. It might have been North America’s tallest building. Unfortunately (perhaps), this project was canceled at the beginning of 2010.

At any rate, Calatrava’s works also include a number of three bridges in Dallas, over the Trinity River. However, the building of the very first bridge, called Margaret Hunt Hill Bridge after its donor, was continuously postponed because of financial difficulties again. This has brought up many controversial debates, and critiques..

Another impressive project belonging to the Spanish designer is the Tenerife Concert Hall. The Tenerife Concert Hall is situated in Santa Cruz, Tenerife’s capital, in the Los Llanos area. It is located between the port’s edge and Marine Park and it is a connection between the ocean and the city, being highly appreciated as part of the city.

The Tenerife Auditorium is a building finished in the year of 2003. This building has a very famous organic structure under the form of white-blue sails. The auditorium has a big concert hall, an opera hall and some other smaller rooms. It is one of the city’s emblems and one of the most photographed buildings in the world. It is located close to Santa Cruz of Tenerife port, and therefore it is close to the sea. It represents one of the main tourist attractions in Tenerife and Canary Islands.

Preparation Tips Before Traveling to Your Destination

When going to another place it is important to be prepared when it comes to interacting with the people and how you will maneuver your way around the town or city area. A couple of months before you plan to travel, read up on the place and familiarize yourself with the landmarks around where you will be staying and educate yourself about tourist spots that you must check out. A lot of people have tour guides assigned to them from an agency to help them work their way around the city. I remember when we’d gone to Thailand not knowing the language at all but relying heavily on a tour guide who was able to give us a good chunk of sight seeing memories. Prepare yourself with the kinds of food that is available there since your system and palate may be sensitive to change. Try learning basic sentences of the dialect to help yourself around like in convenient stores or at the mall, so that you aren’t completely handicapped when in a country that doesn’t have English as part of their system. Also remember to look up certain traditions and cultural habits so that you aren’t breaking any of these valued beliefs, especially if it is a conservative and traditional country.

Things to Pack for an Overseas Trip

Besides knowing what to pack, it is also crucial to know how to pack light for an overseas trip since the last thing anyone wants, is to be weighed down by unnecessary luggage. So let’s look here into the following overseas adventure travel guide on what you must have with you before you set out on your trip. You’ll find here a checklist of items to take and pack into your suitcase, where it is important to keep things like your passport, foreign currency, keys, visa (if any) and credit cards in your handbag.
